Graham leading the group

So far, Corey Graham has been the best cornerbacks in training camp. He always has his hands on a receiver and is in position to make a play. He is one of the few cornerbacks who can turn, find the ball and either pick it off or knock it down. Off the field, he is one of the team's top ambassadors.

I admire James Ihedigbo for holding onto his starting safety position even though he has had a stiff challenge from rookie and top pick Matt Elam. Elam covers more ground but Ihedigbo has more experience and tackles like Ronnie Lott. But it's only a matter of time before Elam takes over. After all, he was the Ravens' No. 1 pick in 2013.
